Which party will gain most seats in Russian Parliamentary Election?

Platform comparison

Market context

Polymarket currently prices this contract at a **68% implied probability** that one party will gain the most seats in Russia’s next State Duma election, with settlement tied to the outcome recorded on Polygon in USDC via conditional tokens. In practical terms, traders are betting on the party that finishes with the largest seat increase versus its pre-election position, not simply the party with the most seats overall.

United Russia remains the reference point for reading that price. Recent polling and seat projections still show it dominating the chamber, with FOM-based estimates putting the governing parties on 69.3% of seats and United Russia alone on 243 projected seats, while other trackers also model a comfortable majority for the party. That matters for this market because “most seats gained” can favour the incumbent even if its headline share barely moves, especially if boundary changes, single-member races and opposition fragmentation shift the arithmetic more than voter intention polls suggest.[1][4]

Traders should watch the formal election timetable, candidate registration, district rules and any changes to the seat allocation framework in the run-up to the September 2026 vote. Wikipedia and election references place polling over 18–20 September 2026, with 450 Duma seats at stake, and the CEC has already registered the United Russia federal list.[6][11] Any late changes to registration, turnout administration or the composition of the ballot could affect how the “gain most seats” comparison is ultimately read at settlement, while the market will otherwise sit on the closed, on-chain Polymarket outcome until the result is known or the fallback date is reached.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.

Resolution & payout

Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.

Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
